With the technology rapidly changing, ultrasonic water meter is widely used in residential, commercial and industrial purpose. To ensure precise readings, it is essential to regularly calibrate and test these meters, in recent years, we have made significant improvement on the technology of ultrasonic water meter testing. We have designed for weighing method and piston method double standard structure, giving full play to the advantages of each standard, if you want to test both mechanical water meter and ultrasonic water meter, this full automatic test bench is a perfect choice.
With competitive price and timely delivery, TNMA sincerely hope to be your supplier and partner.
The new innovation technology specialize designed for Ultrasonic water meter.
Piston:DN15~DN25,12L piston,
DN15~DN50,22L piston
Strengths of piston.
1.Precise flow control: The movement of the piston can achieve more precise flow regulation and control, which helps improve the accuracy and reliability of water meter testing.(Ultrasonic water meter have strict requirement on small fow rate testing,piston make more accuracy testing of Q1 and Q2).When we test flow rate of Q1 and Q2,we use piston,the computer can automatic adjust the valve to control flow rate,manual adjust of valve is not needed,how many water should push from the piston full automatic controled by computer.
2.High durability: Pistons are usually made of wear-resistant and corrosion-resistant materials, have a long service life, and can maintain good performance in frequent testing operations.
3.Good stability: The structure of the piston helps maintain a stable working state during the testing process, reducing measurement errors caused by unstable components.
DN15~DN25
The device Q1 to Q2 is verified by piston, which has many advantages such as wide flow range, stepless flow regulation, accurate flow detected point, fast flow regulation, good flow stability, low energy consumption, low noise and high verification efficiency; Q3~Q4 using weighing method for verification, dynamic commutation, to ensure sufficient stability of the electronic water meter time and water consumption. The piston device can be traced to the weighing method, and the comprehensive performance of the whole device has the international advanced level. The calibre of the device is DN15 ~ DN25(½'~1'), and the flow range is (0. 002~8) m3/h. It can carry out the verification work of mechanical impeller type water meter, ultrasonic type water meter and electromagnetic type water meter.
DN15~DN50
The device is designed with a dual standard structure incorporating both the gravimetric and piston methods, leveraging the advantages of each standard. The device uses the piston method for Q1 to Q2, offering a wide flow range, stepless flow adjustment, accurate flow measurement points, rapid flow adjustment, good flow stability, low energy consumption, low noise, and high verification efficiency. For Q3 to Q4, the gravimetric method is used, featuring dynamic switching to ensure sufficient stabilization time and water volume for electronic water meters. The piston device can be traced back to the gravimetric method, and the overall performance of the device is at an internationally advanced level. The device is designed for verification diameters of DN15 to DN50 and a verification flow range of (0.001 to 50) m³/h. It can be used for the verification of mechanical impeller water meters, ultrasonic water meters, electromagnetic water meters, and more.
